Q. Is power better in a data center? A. Yes. Energy is another important issue for every data center to review. In a data center, power is closely managed and monitored. Often multiple power grid connections and redundant power wiring is used to ensure high availability of power to network resources such as servers, routers, and switches. Data center per-cabinet power consumption has steadily increased over the past several years as pedestal servers drawing 1KW/rack have given way to 1U/2U pizza box servers at 3.5KW/cabinet and blade implementations at 10KW/cabinet. Faster CPUs, larger memory chips, and smaller disk drives also continue to increase power demands. There are 10 key issues for IT managers to keep up with: virtualization; the data deluge; energy and green IT; complex resource tracking; consumerization of IT and social software; unified communications; mobile and wireless; system density; mashups and portals; and cloud computing. The rise in technology and a changing corporate landscape have presented data center operators new challenges. Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later. With fewer servers, you can spend less time on the manual tasks required for server maintenance. On the flip side, pooling many storage devices into a single virtual storage device, you can perform tasks such as backup, archiving and recovery more easily and more quickly. It’s also much faster to deploy a virtual machine than it is to deploy a new physical server. There are many ways that users can corrupt or lose information, including inadvertent file deletion, inadvertent file overwrites, new software installs, lost or stolen computers, hardware failures, virus or hacker attacks and natural disasters. The Cisco UCS uses three adapter types, with four specific models: the Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter, UCS M71KR-Q QLogic Converged Network Adapter, UCS M71KR-E Emulex Converged Network Adapter, and UCS M81KR Virtual Interface Card. Each of these cards has a pair of 10 Gigabit Ethernet connections to the Cisco Unified Computing System backplane that support the IEEE 802.1 Data Center Bridging function (formerly called Cisco Data Center Ethernet) to facilitate I/O unification within these adapters. On each adapter type, one of these backplane ports is connected through 10GBASE-KR to the A-side I/O module; then that connection goes to the A-side fabric interconnect. 10GBASE-KR is a copper midplane technology for interfacing adapters and switching elements through these midplanes. The other connection is 10GBASE-KR to the B-side I/O module; that connection then goes to the B-side fabric interconnect. Figure 3 later in this document shows this connectivity. The Green IT approach can include several different phases in the lifecycle of a product – the development, production, usage and disposal of IT. Development must grant consideration to the environment; the production must take place using environmentally friendly production methods; the IT solutions must be used in an environmentally friendly manner; and finally, IT waste must be disposed of in an environmentally correct manner. All of these phases are supported by research and innovation in Green IT. The data storage system may further include a third arbiter for controlling communication of data from the first storage processor and the second storage processor to a third group of disk drives of the disk drive array. Selected data isredundantly stored on disk drives in the first group of disk drives, the second group of disk drives and, the third group of disk drives such that, upon failure of the first arbiter, the selected data is available to the first storage processor and thesecond storage processor through the second and third arbiters. Nexus sets the stage for converged Fibre Channel and Ethernet networks. The Nexus products will allow companies to consolidate their separate server and storage networking infrastructures onto one unified network fabric. |
